Protecting Public Health and the Environment.
Because most hot-mix asphalt plants have specific pieces of permitted equipment, DEQ has created a streamlined permitting process for these operations. This permitting process includes the following steps:
Prior to submitting an application for a new or modified asphalt plant, call the Air Quality Permitting Hotline at 1-877-5PERMIT (573-7648). This will put you in touch with a DEQ permit writer who can answer any questions you might have about the air permitting process. Although it’s not required, it is strongly recommended that at this time you request to schedule a pre-application meeting with DEQ to discuss the permitting process and your project.
The pre-application meeting may be held in person or via conference call. During this meeting, the three main components of the permitting process and the likelihood of submitting a complete permit application will be discussed. The three main components of a complete application are the emissions inventory, the regulatory review, and air dispersion modeling. (For modeling protocol questions contact Kevin Schilling, DEQ Modeling Coordinator, at (208) 373-0112 or email@example.com). The modeling protocol will need to be developed, using DEQ’s HMAP (Hot Mix Asphalt Plant) form, prior to submission of the application package.
With respect to the emissions inventory, if you plan to propose using used oil or recycled fuel oil as burner fuel for the drum dryer, the minimum fuel sulfur content available on the open market is 0.1 percent by weight. This sulfur content must be used in the calculations to estimate sulfur dioxide emissions from the hot-mix asphalt drum dryer stack.
Prior to attending the pre-application meeting with DEQ, the applicant will need to review DEQ’s Modeling Setbacks document. This document provides rough estimates of the required setback distances for new or modified hot-mix asphalt plants using different operating scenarios. Reviewing this document will help the applicant decide on the appropriate operating scenario to apply for.
The application fee is $1,000, which may be paid by check, credit card/E-check, or bank wire transfer.
